"Very well, then," Martin said triumphantly. "You're going to impress the character-matrix, of Ivan the Terrible on my mind, and then I'm going to put the bite on St. Cyr, the way Ivan would have done it. Disraeli's simply too civilized. Size is a factor, but character's more important. I don't _look_ like Disraeli, but people have been reacting to me as though I were George Arliss down to the spit-curl. A good big man can always lick a good little man. But St. Cyr's never been up against a really uncivilized little man--one who'd gladly rip out an enemy's heart with his bare hands." Martin nodded briskly. "St. Cyr will back down--I've found that out. But it would take somebody like Ivan to make him stay all the way down." "If you think I'm going to impress Ivan's matrix on you, you're wrong," the robot said. "You couldn't be talked into it?" "I," said ENIAC, "am a robot, semantically adjusted. Of course you couldn't talk me into it." Perhaps not, Martin reflected, but Disraeli--hm-m. "Man is a machine." Why, Disraeli was the one person in the world ideally fitted for robot-coercion. To him, men _were_ machines--and what was ENIAC? "Let's talk this over--" Martin began, absently pushing the desk-lamp toward the robot. And then the golden tongue that had swayed empires was loosed.... "You're not going to like this," the robot said dazedly, sometime later. "Ivan won't do at ... oh, you've got me all confused. You'll have to eyeprint a--" He began to pull out of his sack the helmet and the quarter-mile of red ribbon. "To tie up my bonny grey brain," Martin said, drunk with his own rhetoric. "Put it on my head. That's right. Ivan the Terrible, remember. I'll fix St. Cyr's Mixo-Lydian wagon." "Differential depends on environment as much as on heredity," the robot muttered, clapping the helmet on Martin's head. "Though naturally Ivan wouldn't have had the Tsardom environment without his particular heredity, involving Helena Glinska--there!" He removed the helmet. "But nothing's happening," Martin said. "I don't feel any different." "It'll take a few moments. This isn't your basic character-pattern, remember, as Disraeli's was. Enjoy yourself while you can. You'll get the Ivan-effect soon enough." He shouldered the sack and headed uncertainly for the door. "Wait," Martin said uneasily. "Are you sure--" "Be quiet. I forgot something--some formality--now I'm all confused. Well, I'll think of it later, or earlier, as the case may be. I'll see you in twelve hours--I hope." The robot departed. Martin shook his head tentatively from side to side. Then he got up and followed ENIAC to the door. But there was no sign of the robot, except for a diminishing whirlwind of dust in the middle of the corridor. _Something began to happen in Martin's brain...._ Behind him, the telephone rang. Martin heard himself gasp with pure terror. With a sudden, impossible, terrifying, absolute certainty he _knew_ who was telephoning. _Assassins!_
